Answer: There are 152 adults and 87 children.
Step-by-step explanation:
Let x= Number of adults
y= Number of children
As per given, we have
x+y = 239 (i)
15x+5.50y= 2758.50 (ii)
Multiply 5.50 on both sides of (i) , we get
5.50x+5.50y=1314.5 (iii)
Subtract (iii) from (ii), we get
9.5x = 1444
⇒ x = 152
Put value of x in (i) , we get
152+y=239
⇒ y= 239-152
⇒ y= 87
Hence, there are 152 adults and 87 children.
I'll do it with a fraction, so let's say 15/45. 15 of the cards are baseball cards, 30 of them are other cards. I would say 15/45, because 45 is the total amount of the cards he has. Only 15 are BASEBALL cards, so it would make sense to say he has a 15/45 chance to pull a baseball card.
There isn't an exact value for the square root of 3. It is roughly 1.732
